Doug Heffernan puts in a long day's work delivering parcels and comes home each night to his loving wife, Carrie; unfortunately, he also comes home to his wacko father-in-law, Arthur.

Doug's bowling-team sponsor demands victory, meaning Doug may have to fire his team's weak link: his wife, Carrie.

Carrie helps Doug plan a bachelor party after she volunteers him to be the friendless Danny's best man.

Doug tries to be romantic by making an unexpected appearance at Carrie's company retreat; Danny and Spence sneak into a Huey Lewis concert.

Carrie wants to put Arthur in a retirement home after he starts a fire in the basement, but Doug makes a discovery that makes him want to change her mind.
